Subject: [PATCH] ASoC: soc-devres: Remove unused devm_snd_soc_register_dai

From: "Dr. David Alan Gilbert" <linux@...blig.org>

The last use of devm_snd_soc_register_dai() was removed by
commit fc4cb1e15f0c ("ASoC: topology: Properly unregister DAI on removal")
in 2021.

Remove it, and the helper it used.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
